60 Centuries of Copper: The Flotation Process

Only the flotation process mentioned above could make this practicable; and even so, it requires large companies with huge plants, continuous working and immense capital. This explains why, in order to smelt 4 million tons of new copper in 1963, nearly 400 million tons of ore had to be handled and treated in various ways. Flotation depends on ...

A review of mineral processing of ilmenite by flotation ...

Oct 01, 2020  It is hypothesised that the activation of ilmenite flotation by copper (Cu) ions when using HPA as the collector is a combined process of ion exchange, metal hydroxides adsorption, and redox processes (Li et al., 2016). As a result, the low-active ilmenite surface is converted into high-active status for subsequent collector adsorption. 3.4.1.4.
